摘要 碳排放是全球气候变化研究的重要内容,科学厘清碳排放与经济增长的时空耦合关系对促进区域生态文明建设和经济高质量发展具有重要意义.以黄淮海地区为例,运用空间自相关分析、热点探测、耦合协调模型等方法分析2000-2020年黄淮海地区碳排放与经济增长时空耦合关系.研究结果表明:(1)2000-2020年黄淮海地区碳排放量与经济增长总体上呈现持续增长态势,2000-2010年碳排放与经济增长的速率高于2010-2020年.(2)2000-2020年黄淮海地区碳排放与经济增长呈现显著的空间集聚特征.碳排放热点区主要集中于北京市、天津市、河北省、山东省境内,范围不断收缩,冷点区主要分布于河北省南部;经济增长高值集聚区主要分布于北京西南部、天津沿海、河北东北部及河南省内,低值区主要分布于河北省、河南省、山东省、安徽省内.(3)2000-2020年黄淮海地区碳排放与经济增长整体处于勉强协调等级,耦合协调度时空差异显著,总体呈现东高西低、北高南低的空间格局.良好与基本协调区主要分布于京津冀地区,轻度与严重失调区趋于山区、省域边缘区分布态势,零散分布于山东、河北、河南、安徽省内. Carbon emissions are an important part of global climate change research.Scientifically clarifying the spatiotemporal coupling relationship between carbon emissions and economic growth is of great significance to promote regional ecological civilization construction and high-quality economic development.Taking Huang-Huai-Hai Region as an example,spatial autocorrelation analysis and coupling coordination model were used to analyze the spatio-temporal coupling relationship between carbon emissions and economic growth in Huang-Huai-Hai Region from 2000to 2020in this study.The results showed that:(1)From 2000to 2020,the carbon emissions and economic growth in the Huang-Huai-Hai Region generally showed a sustained growth trend,and the rate of carbon emissions and economic growth from 2000to 2010was higher than that from 2010to 2020.(2)From 2000to 2020,Huang-Huai-Hai Region showed significant spatial agglomeration in carbon emissions and economic growth.The hotspots of carbon emissions were mainly concentrated in Beijing,Tianjin,Hebei and Shandong,showing a shrinking trend,and the cold spots were mainly distributed in southern Hebei Province;as well as the high economic growth clusters were mainly concentrated in southwest Beijing,coastal Tianjin,northeastern Hebei and Henan Province,while the low economic growth clusters were distributed in Hebei,Henan,Shandong and Anhui Provinces.(3)From 2000to 2020,overall coupling relationship of carbon emissions and economic growth were barely coordinated in the Huang-Huai-Hai Region.The overall spatial pattern was high in the east and low in the west,and high in the north and low in the south.The coordination regions with good and basic level were mainly distributed in the Beijing-Tianjin-Hebei Region,while the imbalance areas with mild and severe level tended to be distributed in mountainous areas and provincial marginal areas,which were scattered in Shandong,Hebei,Henan and Anhui Provinces.
